Abstract: A pipe connection structure for a vacuum-type sewage collecting apparatus for collecting sewage discharged from a multiplicity of houses (30) or facilities in an accumulating tank (41) through a vacuum sewage pipe (1) the inner pressure of which has been made to be a negative level is disclosed. The vacuum sewage pipe includes a plurality of upper stream pipes and lower stream pipes fastened to each other in the branch-like shape. The pipe connection structure connects the upper stream pipe (1-2) to the lower stream pipe (1-7) formed in a sawtooth-like shape by alternating a downward-slope portion (11), which is arranged to slope gently downwards toward said accumulating tank (41), and a lift portion (12) fastened to the lowermost portion of the downward-slope portion (11) and arranged to be a steep upward slope. The upper stream pipe (1-2) is connected to the lower stream pipe in a range in which a horizontal plane, which is positioned in contact with an upper end portion (13) of the lower stream pipe (1-1) at the position in which the downward-slope portion (11) changes to the lift portion (12), is higher than the center of the lower stream pipe (1-1) and at a position in which an opening of the upper stream pipe (1-2) opened in the lower stream pipe (1-1) is positioned diagonally upper than the pipe center of the lower stream pipe (1-1) in a plane perpendicular to the pipe central axis. At least a portion of the opening is higher than the horizontal plane, and the upper stream pipe extends from the lower stream pipe diagonally upwards. By this arrangement, upper and lower stream pipes can be connected to each other in such a manner that the level difference between the two pipes can be significantly reduced and the back flow of sewage from the lower stream pipe toward the upper stream pipe can be prevented.

Abstract: The invention relates to a process for making membranes of bacterially produced cellulose and to the use of these membranes for separation operations such as, for example, for microfiltration or ultrafiltration. Cellulose-forming acetic acid bacteria are caused to grow at temperatures between 18 and 35 DEG C without immersion in non-agitated cultures at pH values between 5.5 and 6.5 on nutrient media which contain carbon sources utilisable by the bacteria, utilisable proteins and nutrient salts, the morphologically inhomogeneous cellulose layers which may have been formed by the bacteria on the nutrient media during an exponential growth phase of the bacteria are removed and discarded, and the morphologically homogeneous cellulose layers formed by the bacteria on the nutrient media during the steady growth phase of the bacteria are isolated and purified. Depending on the nutrients available to the bacteria, cellulose membranes of in each case homogeneous fibrillar or globular structure are obtained. At constant availability of nutrients, cellulose membranes of homogeneous layer thickness are obtained.

Abstract: According to a gear shift control system of a continuous transmission of the present invention, when the gear ratio is controlled to a target gear ratio, a deviation between an actual primary pulley speed and the target primary pulley speed is detected. When a feedback-control is carried out to control the actual primary pulley speed to the target primary pulley speed on the basis of the above deviation, the control gain(s) is changed according to the deviation between the actual and the target primary pulley speeds at changing the gear ratio. Thus, the gear ratio is changed at the constant speed and better gear characteristics can be gained. Moreover, the hunting of the actual primary pulley speed occurred around the target speed can be prevented.

Abstract: Units having a beam-scanning function, and a light-receiving function and a photoelectric-­conversion function are separated from the main-body (16) of a stationary-type bar code reader as a separation unit (17). The separation unit (17) is detachably mounted on the main-body unit (16). The separation unit is mounted on the main-body unit for use as a stationary-type reader when a product on which a bar code is printed is relatively small and light. When a product is large or heavy, the separation unit is separated from the main-body unit for use as a hand-held reader. This improves the operability of the bar code reader and eliminates the need to equip a stationary bar code reader and a hand-held bar code reader separately.

Abstract: A hand-operated sand-blasting tool works with a blasting-agent cartridge 20 which can be inserted into its handle part 10 and is sealed off to the rear by a piston 34 which can be displaced by compressed air. A portion of the compressed air flows through a longitudinal groove 25 in the wall of the handle part past the outside of the cartridge 20 and passes through a bore 27 at the front end of the cartridge in that area in which the relatively large cross-section of the main part of the cartridge narrows down to the substantially smaller cross-section of a feed passage 28. The blasting agent 21, present in the form of a powder or very fine sand, is thereby fluidised and kept fluidic in this area. The blasting agent flowing in via the feed passage 28 is mixed with compressed air in a mixing chamber 30 and is fed by a nozzle tube 33 to the treatment point.

Abstract: The positioning device serves to position two components (2, 2') relative to one another and has a positioning part (4) which lies in recesses (3, 3') of the components. The positioning part (4) bears against a centring face (17) of one component and is elastically deformed when the components are joined together. The centring face (17) is provided on a disc spring (16) which, when the components (2, 2')are joined together, is elastically deformed in the direction of its planar form and is supported on the side wall of the recess (3). Very high pretensioning forces can be produced by the disc spring (16, 16') so that even heavy components can be positioned satisfactorily and in a highly accurate manner. The disc spring (16, 16') has high rigidity in the face of transverse force so that heavy varying weights can be absorbed by the positioning elements even in the case of a vertical attachment. The positioning device is self-centring due to the pretension so that the joining operation can take place with maximum repeatability. During the elastic deformation, any radial residual play between the disc spring (16, 16') and the recess (3, 3') is reliably eliminated. <IMAGE>

Abstract: In a novel fibre-optical differential refractometer (FODR) for measuring the increment Dn in refractive index or the difference DC in concentration, light from a light source 1 is coupled into the gate I of a fibre-optical directional coupler 2, and then directed into a gate II through the directional coupler 2. The light is collimated by a lens 3 at the end of gate II. The collimated light is further directed through a split refractometer cell 4, and retroreflected by a mirror 5. The reflected light is directed once again through the split refractometer cell 4. The light is refracted upon each passage through the refractometer cell 4 if the solutions in the two compartments of the split refractometer cell 4 have different refractive indices. Consequently, only a fraction of the reflected light can be focused by the lens 3 into the gate II, and this fraction is, in turn, a function of the extent of the refraction. The light received by the gate II is directed further by the directional coupler 2 to the photodetector 6. <IMAGE>

Abstract: An electrophysiologically guided arrhythmia ablation system for ventricular tachycardia or other arrhythmias. The system combines a system for recording the electrical activation time of various parts of the heart for locating an active site of the arrhythmia, with a system for delivering energy for ablation of the arrhythmia. The system has the capability of processing local myocardial electrical activation data and triggering the ablation energy source when at the active site or inhibiting the release of potentially harmful energy when the device is not at an active site. The process includes identification of an active site which occurs during the 20-80%, preferably 35-50%, time period of a diastolic interval. The diastolic interval is monitored by appropriate electrical connections between the heart and a monitor. A mapping device also connects to the monitor which maps for indicating an active site. The active site is then a site for preferred placement of an electrode for a defibrilator. A timing system connects to the monitor, indicates when an active site is located in the 20-80%, preferably 35-50%, of the diastolic interval, and also connects to a laser system for firing the laser system to ablate the active site. Other ablate energies can be utilized including RF, microwave or DC energy.
